Serial No. 509,914.

This invention relates to a poweroperated shovel that may Aloe mounted upon a truck E and operated by iiuid under compression,

panying drawings in which Fig. 1 is aside such as compressed air, to load and unload the same. The shovel is mounted upon a revolving frame or turn-table and is supported upon a pivoted support so that the shovel may be loaded and unloaded by movement of the shovel in a single plane', or the shovel may be turned intodierent positions for unloading it.

The invention wiil be understood from the description in connection with the accomelevation of an illustrative embodiment of the invention; Fig. 2 is a front view; Fig. 2a is a section through one 'of the parts; Fig. 3 is a rear view and Fig. 4 is a planview of the same.

1n the drawings reference character 1 indicates a truck that is provided with Wheels 2. A stationary platform 3 is provided upon the truck and a motor 4 is mounted on the platform and is provided with a pinion d that meshes with the gear 5 along the periphery of a turn-table 6 that revolves around a vertical king holt 7 on the platform 3.

A horizontal shaft 3 is journalied in hearings in the side trames 8 ned on the tnrn.

table 6. Rods 9 are pivoted aty their `loafer ends on the shaft 8 and are provided attheir upper ends with journals 10 in which the shaft 11 is journalled, this shaft being parallel to the shaft 8.

'A cylinder 12, which may have its voutside rectangular in cross section, as shown in Fig. 2a is provided with an elongated transverse hollow lug 13 through which the shaft 11 extends, thus ivoting the cylinder 12 upon the shaft 11. atensions 14 slidablein grooves 14 are provided along the lower portion or the cylinder 12 to serve as supports, upon 'which the shovel or digging element 15 is supported and canbe moved back and forth. The shovel 15 is provided with a lug 16 that is connected by means of the piston rod 17 to i thepiston 18 inside the cylinder 12. The cylinder 12`1s"'of"awell known type in which Huid such as air under compression canbe admitted to opposite ends thereof for mpv` ing the piston 18 back and forth, thus moving the shovel 15 longitudinally into different positions along the supports 111. The means for admitting the fluid to the cylinder 12 have been omitted to avoid confusion. of the drawings, as this is well known in the art. The upper end of the cylinder 12 is provided with a head 19 having a recess to fit upon the shaft 8, as will be explained below. ,The head 19 is provided with a cross pinv20 to which the end of acable 2l is attached. The cable 21 passes around a'sheave 22 on the shaft 8 and thence around a drum 23 on a shaft 23 journalled in the side plates 8. A. gear 24 is rigidly connected to the shaft 23 and is driven by a pinion 25 mounted on the shaft 26 that is journalled in bearings at the upper portions of the side plates 8s. Crank pins 27 are connected to dywheels 28 on the shaft 26 and piston rods 29 connect the crank pins 27 to the pistons in the cylinders 30 that can be operated in the Well-known manner by uid un-v .shaft 26. The cylinders 30 lare mounted in xed .positions upon the side frames 8. rl"he shaft 26 carries cams 31 for operating the mechanisms 32 for admitting duid to oppon site ends o the cylinders 30.

A clutch 33 is provided on the shaft 23 and is operated by the handle 311 for connecting the drum 23 to the driving mechamsm. l v

Two cylinders 36,'each provided `with a lug 37, are ivoted on a shaft 38 supported byk the side rames 8. The cylinders 36 are provided with pistons that may be reciprocated similar to the Way the pistons in the cylinders 12 and 30 are reciprocated. The pistons in the cylinders 36 are connected by the piston rods 39 and journals 40 to the shaft 11.

The operation is as follows:

,The device is brought near the material, such as a rock pile, for example, that is to be loaded upon a truck or the like, with the parts in the position indicated by solid lines in Fig. 1. Air is admitted to the cylinders 30, thus driving the shaft 26, pinion 25, gear 24 and drum 23 when the clutch 33 is operated. This cause'sthe cable 21 to be wound lupon the drum 23 drawing the upper end of thus pushing or crowding the shovel into the mass of material. The winding of the cable 21 is continued until the recess in the head 19` fits over the shaft 8 whereu on the cylinder 12 is approximately paralle to the rods 9.

Air is then admitted to the lower ends of the cylinders 36, thus moving the pivot shaft 11- through an arc of a circle whose center is the shaft 8. The dotted line position of the rods 9 and cylinder 12 in Fig. 1 indicates a position into which the shovel 15 has been carried after it has been loaded. The truck upon which the material is to be loaded may be placed behind the device on the side opcposite the pile of material that is being loa ed and a slightly further movement of the cyliss inder 12 than that shown in dotted lines in Fig. 1 will cause the material to slide out oi the shovel 15 onto the truck. However, the truck may be placed alongside of the device and after the shovel is loaded the tum-table 6 may be turned by means of the motor l to direct the cylinder 12 over the truck when the cylinder is turiicdto the unloading position.

I claim:
